Application filed November 4, 1915. Serial No. 59,608.

' lportable conveyers and its object is to produce a device of thisclass adapted primarily for use in loading or unloading freight carsalthough it may be employed for other purposes. Means for adjusting thedevice longitudinally as well as transversely also -form a feature ofthe invention. vith the foregoing and other objects in view theinvention consists in the combination and arrangement of parts to behereinafter fully described in the following specification, pointed outin the appended `claims and illustrated in the accompanying"r drawingswhich form a part of said specification and in which Figure 1 is avertical sectional view through a freight car showing the application ofmy invention which is shown in side elevation.

Fig. 2 is' a top plan view of the device, the car being shown inhorizontal cross section.

Fig. 3 is a view partly in section and partly in front elevation and istaken on line 3-3 of Fig. 1.

Fig. 4 is a section'on line 4 4 of Fig. 6. Fig. 5 is a verticalsectional view on line 5 5 of Fig. 3.

Fig. 6 is a vertical sectional view on line 6--6 of Fig. 3.

Fig.. 7 is a View, partly in section, through the,top that may beemployed to protect the working parts from the weather when inoperation. A

Fig. 8 is a cross section through- Fig. 2 on lin'e 8-8.

Fig. 9 is a section on line 9-9 of Fig. 8.

Fig. 10 is an enlarged plan view of a portion of the track.

Fig. 11 is an enlarged sectional view on line 1'1-11 of Fig. 10.

Fig. 12 is an enlarged view of a modified form of--chain tightener thatmay be employed.

Like reference characters indicate correspondingv parts throughout theseveral views.

Y lower ends of the The reference numerals 1 denote adjustabletelescoping legs whichV stand upon bases 2 and are connected by braces 3and said legs carry the transverse shafts et whereon longitudinallygrooved blocks 5 are supported that carry the ends of theconveyerbed-sections G which telescope into the said blocks. By movingthe bed sections toward each other, or into the blocks 5, the length ofthe conveyer is decreased and by moving. the bed sections away from eachother or partly withdrawing them from the grooved portions of the saidblocks ,the length of the conveyer is increased. In Fig: 'I

S of the drawings the manner of disposing the bed sections in the blocks5 is clearly" shown, said bed sections being T-shapedvin cross section.Tothe bed sections the track 7 is secured over which the conveyer chain8 travels that carries the merchandise 9 from the point of loading tothe point of unloading. Upon the said shaft 4 a plurality of blocks 5are arranged and the coni'cycr chains, two in number, are adapted'to beremovably arranged to travel over 'any two of said blocks or over anytwo sets of bed sections thereby making thewidth of the conveyeradjustable. The conveyor chains run from the bed sections over the cogs10 loose upon a transverse shaft 11 opposite one end of said sectionsand over similar cogs arranged upon another verse shaft 12 opposite theother end of the bed sections, which form the conveyer bed.

rEhe said sha-ft 11' terminates in a square' end adapted to receive thecrank or handle 13 whereby it may be rotated to rotate larl e cogs 111arranged between the ends of braciets 15, in which said shaft 11 isjournaled, which brackets are slidably arranged upon racks 16 the teeth17 of which are in mesh with the said cogs le whereby vone end of theconveyer is raised or lowered. A pawl 18 carried by one bracket 15engages a ratchet 19 on shaft 11 to retain said shaft in adjustedrelation with the racks. The. racks 16 are preferably beveled to engagewith the door. guide bar 20 of the car 21 and the upper endsof saidracks are slotted longitudinally as at. 22 to receive pins carried bythe angular arms 23 which may be Inovably secured to one vside transv ofthe car 21 by the adjusting screws 2li 5 In a suitable framework theengine 26 is supported, the piston 27 of which is cony nected to aneccentric on a transverse shaft 28 which shaft also carries a cogwheel29- in mesh with a cog wheel 30 vof shaft 12 -whereby lsaid shaft isrotated to drive the conveyer chains. The said blocks 5 that aresupported by one pair oflegs 1 are pro# vided with adjustable chaintighteners comprising wheeled racks 3l adapted for en'- 'gagement withpawls 32 to retain them in adjusted relation; or said racks may be displaced by wheeled arms 33 connected by springs 3l. with legs 1;` thisform of .chain tightener being automatic 1n its action. An-v other setof blocks 5 (see Fig. 1) is provided with the chain guides 36 whichafgonveyer is not in use and it isdesired-to move it from place to placethe said legs may befpartially telescoped to permit the wheels 41 tocarry the Weight of the conveyer which may then readlly be'moved asdesired, together With the engine frame provvided with Wheels 42.

What is claimed is 1. In a conveyer comprising conveyer-bedsections,blocks adapted to carry the ends of said conveyer bed sections, legs forsaid blocks, transverse shafts arranged opposite.

the ends of said conveyer-bedsections, cogs carried by said shafts,conveyer chains arranged to travel over said cogs and over saidcenveyer-bedsections, and driving means for said cogs.

2. In a conveyer comprising conveyer-bedsections, blocks adaptedA totelescopically carry the ends of said conveyer-bed-sections, verticallyadjustable legs for said blocks7 t `ansverse shafts arranged oppositethe ends of said conveyer-bed, cogs carried by said shafts, eonveyerchains arranged to travel over said cogs and over lsaid conveyer-bedsections, and driving means for said cogs.

In a conveyer comprising conveyerbed-sections, longitudinally groovedblocks adapted 'to adjustably carry the ends of saidconveyer-bed-sections, vertically adjustable legs for* said blocks,transverse shafts arranged oppositc the ends of the conveyer-bed formedby saidv conveyer-bed-sections, cogs carried by said shafts, conveyerchains a-rranged to travel over said cogs and over saidconveyer-bed-sections, autolnatic chain tightening means carried by saidblocks for engagement with said conveyer chains, and driving means forsaid cogs. i

4. In a conveycrcon'iprisingsconveycr-bedsections, parallel blocksarranged in series and adapted 'to telescopically carry the ends of saidconveyer-bed-sections, vertically adjustable legs for said blocks,,transverse shafts arranged opposite the ends of said' conveyerbcd, cogscarried by "said shafts in alinement with the said'parall'el blocks,conveyer chains arranged to travel interchangeably over said cogstandover said conveyerbedsections, and; driving means for said cogs.

In testimony that l claim the foregoing as my own I have hereto aiiixedmy signature in the presence of twosubscribing witnesses.
